daniel,

i tried

	$rU = null;
	xlog("L_INFO", "Request URI <$ru>\n");
	if ($(rU{s.len}) == 0) {
		xlog("L_INFO", "Length is 0\n");
	}
	if ($(rU{s.len}) == 1) {
		xlog("L_INFO", "Length is 1\n");
	}
	xlog("L_INFO", "Length is $(rU{s.len})\n");
			
	sl_send_reply("500", "Testing\n");
	exit;

with tonight's svn trunk version and got:

Jul  9 21:59:06 localhost /usr/sbin/openser[23658]: Request URI <sip:test.fi>
Jul  9 21:59:06 localhost /usr/sbin/openser[23658]: comp_scriptvar: cannot get left var value

in order to get rid of the error messages, i would need to test if $rU
is not null before trying to get its length.

i would prefer to be able to use null value also in expressions without
error messages.
